Your heard us. A fish tank is actually a double-whammy of bad WiFi because not only do you have the electrical circuits powering the tank but then the enormous body of water that’s absorbing the signal being given out by the router.

Walls

This sounds like a no-brainer but looking at the layout of your house and working out where walls could block your router’s signal could make all the difference. Almost a quarter of those asked in the survey have admitted to putting their router by a window (bad), shared wall (worse) or even at the top of their house (just no).

Instead if you can, make sure the router is given space on all sides, is centrally located within the house and isn’t just kept in a corner whee no-one can see it.

Christmas lights

You can probably see where we’re going with this. Christmas lights, although pretty, are a giant flashing nightmare for your WiFi. They’re one big wrapped up electric interference device and so if you’re going to get festive, try and keep your router as far away as possible.
